Claims. 1

This invention is directed to new and useful improvements in impulse regulator assembly of the type wherein pulsating pressure is provided to a pump assembly to move liquid from below ground to a storage tank or the like.

This device is particularly adaptable for use in a pump mechanism of the type in which a column of liquid leading from the top of a well to the source of supply is provided near the bottom with means whereby liquid from the source is entrapped each time a downward impulse is exerted on the column and, at the same time, a spring or a volume of air is compressed so as to add the thus entrapped liquid to the column when the downward impulse is released, whereby there is delivered to the surface an amount of liquid equivalent to the amount entrapped by the downward impulse. It is through a series of regular impulses that a steady flow of liquid is brought to the surface for delivery to a storage tank or elsewhere as desired. In such a device it is desirable to provide an eiiicient valve assembly cooperating with the pulsating means to direct pressure on the liquid column, to lead the pumped liquid to its reservoir, to prime the liquid column when necessary and to direct pressure so as to aid the pulsating means so that it may be actuated by less power.

The primary object of this invention is to provide an impulse regulator assembly of this type wherein passage to the liquid reservoir is adequately closed during exertion of pressure on the liquid column but open on release of the pressure.

Another object of this invention is to provide in such an assembly means for permitting the liquid column to be primed automatically and positively when needed.

A further object of this invention is to provide in such a device an arrangement of parts whereby less power is required to operate the pressure actuating means.

Other objects and advantages will be apparent from the following detailed specification.

In the drawings:

Fig. 1 is a schematic view of an impulse regulator assembly embodying this invention associated with a pump.

Fig. 2 is an enlarged sectional view of the impulse regulator assembly embodying this invention.

Referring to Fig. 1, reference character I designates a well casing within which is suspended an impulse actuated pump mechanism 2 of the type as described in. detail in my copending application Serial Number 680,295 filed June 27, 1946, now Patent Number 2,486,617, containing a reciprocating piston actuated by the variations of pressure on the liquid in the casing. The cylinder 3 houses the pressure means and conduit 4 connects the cylinder 3 with the casing I through a load compensating reservoir or accumulator 5. The valve assembly is in housing 6 connected with cylinder or well casing and a conduit 1 leads to liquid storage tank 3.

The details of the impulse regulator assembly are shOWIl in Fig. 2. A piston 9 is reciprocally mounted in cylinder 3, rod It being of relatively substantial diameter and extending from the cylinder 3 to any desired operating mechanism.

Casing 6 is connected with the open end of cylinder 3 and is divided into main chamber H and outlet chamber [2. Chamber II is provided with a main port It connected with the top end of casing l, a pressure inlet port I l normally closed by valve l5 which is resiliently held in closed position by spring it. A passageway ll leads from the open end of cylinder 3 to port I 4. Chamber [2 is provided with inlet port l8 opening to chamber ll, controlled by valve 19 and an outlet 20 connecting with conduit 7.

Valve [9 has a stem 2| to which is secured a piston 22 of larger diameter than valve l9. This piston 22 is reciprocally mounted in cylinder 23. A passageway 24 leads from cylinder 23 to passageway ll to direct liquid under pressure from cylinder 3 to the rear of piston 22.

A small priming port 25 opens chamber 12 to passageway 24 but is normally closed by valve 26 held resiliently in closed position by spring 21. Aone way valve 28 is positioned in conduit 4 to admit liquid from the casing l but to prevent a reverse flow.

In operation, cylinder 3, casing I, conduit 4, reservoir 5, chamber II and conduit 24 are filled with liquid, e. g. water. Piston 9 is moved in cylinder 3, by any desired means, toward housing 6. The pressure thus created opens valve [5 against the spring It and the pressure is transmitted to the water in the pump casing I to depress the piston in the pump. The pressure is also transmitted to conduit 24 against piston 22 to keep valve [9 closed. This occurs because piston 22 is of greater area than valve It.

The pressure against the Water in the system is directed through valve 23 and conduit 4 to cylinder 3 back of piston 9 to relieve the load.

As piston 9 returns to its initial position the pressure is released, valve [5 closes and pressure within casing l reverses to direct water 3 therefrom to open valve I9 and thus water flows into chamber l2, out of out et 20, through conduit 1 into storage tank 8.

If there is insufiicient water in cylinder 3 and conduit 24, valve 26 will open on this return stroke and water will prime the cylinder.

The relatively large diameter of rod ID decreases the volume of cylinder 3 behind piston 9 so the power required to return the piston to initial position is accordingly decreased.

Also in this reverse cycle of operation, piston 9 returns liquid under pressure through conduit 4. Valve 28 prevents this returned liquid from entering casing I and pressure is built up in reservoir 5. When pressure in conduit 4 and accumulator 5 equals the peak pressure in casing I, this pressure will prevent valve 28 from opening. Several cycles, or forward and backward strokes of piston 9 may be necessary before the pressure in the accumulator equals that of the peak in the well casing. This pressure is utilized against the reduced area of the rear of piston 9 to relieve it of the load on the outward stroke.

Thus an impulse regulator assembly is provided in which less power is required to operate the pressure generating piston, the pressure created by the piston is used to seal the system during its generating stroke and means are provided for automatically priming the system.

The apparatus herein described may be operated successfully without the accumulator 5 and conduit 4. This is an optional addition but when omitted the power of the motor operating piston 9 must be increased. The effectiveness of the valve assembly remains whether or not accumulator 5 and conduit 4 is utilized.
